Abbott Laboratories announced Thursday its over-the-counter continuous glucose monitor Lingo is available in the U.S. starting at $49.
Lingo is part of an emerging class of consumer-friendly biosensors that people can use to learn how their bodies respond to food, exercise, sleep and stress. These devices, called continuous glucose monitors, are small sensors that stick through the skin to measure real-time glucose levels. Glucose is a sugar molecule that comes from food, and it’s the body’s main energy source.
Continuous glucose monitors have served as tools for patients with diabetes, but Lingo is not intended for diabetes management. Instead, it’s designed for adults who do not take insulin and want to “improve their overall health and wellness,” according to a release.
Everyone’s glucose levels fluctuate, but consistently high levels can cause more serious health problems like metabolic disease, insulin resistance and heart disease, Abbott said. The company argues Lingo can educate users about existing habits and help them learn to manage their glucose in healthier ways.
“That’s really the goal, is to not only see and understand what’s happening inside your body, but to be able to improve on that, to be able to build these healthy habits that drive those changes,” Ben Fohner, the director of Abbott’s Lingo app, told CNBC in an interview.
Abbott already offers continuous glucose monitors for diabetes patients in the U.S., so the company is looking to break into an entirely new market with Lingo. About 1 in 3 Americans have prediabetes, for instance, but these patients typically don’t qualify for prescriptions or insurance coverage for the monitors.
Now, they can pay for the sensors out of pocket without a prescription. Users can buy one sensor online for $49, two sensors for $89 or six sensors for $249, Abbott said. Each sensor is worn on the upper arm for up to 14 days.
Olivier Ropars, Abbott’s divisional vice president of Lingo, said the company decided to offer three different pricing options so curious consumers won’t feel intimidated by a lengthy commitment. A customer can opt to buy just one sensor to try for a couple of weeks.
“We want to make it as accessible and affordable as possible,” Ropars told CNBC in an interview.
Abbott’s competitor, Dexcom, is also eyeing the prediabetes market. The company released its over-the-counter continuous glucose monitor geared toward this demographic in late August. Dexcom’s device is called Stelo, and is available in the U.S. for $89 a month. Patients with Type 2 diabetes who do not take insulin can also use it, the company said.
The U.S. Food and Drug Administration approved Dexcom’s Stelo in March, and it cleared two over-the-counter continuous glucose monitoring systems from Abbott in June. One of Abbott’s systems was Lingo, and the second system, called Libre Rio, is intended for patients with Type 2 diabetes who do not take insulin.
Though Type 2 patients who are not taking insulin could technically use Lingo, Ropars said Abbott’s recommendation is to primarily use Libre Rio since it is specifically designed for them. The company declined to share when Libre Rio will be available.

Like many continuous glucose monitors, Lingo transmits data wirelessly to an app. When users open it, they’ll see a real-time reading of their glucose data that’s updated every minute.
Those glucose readings are plotted on a graph, which includes a shaded area to indicate a “healthy range.” Fohner said Abbott’s clinical team defines this range as 140 milligrams per deciliter to 70 milligrams per deciliter.
One of Abbott’s primary goals is to help Lingo users learn about glucose spikes, which occur when the amount of sugar present in the bloodstream rapidly increases and then decreases. Glucose spikes commonly occur after eating.
Spikes can push a user’s glucose reading above the healthy range, but they can also occur within the healthy range. Limiting spikes and improving glucose management overall can help users improve their sleep and mood, manage their weight, and be proactive about their future health, Abbott said.
To help users conceptualize the impact of their spikes, Abbott created a metric called the “Lingo Count.” It’s an algorithm that assigns a numeric value to each glucose spike, and it’s supposed to represent how significant the impact is. Over each day, users have a target Lingo Count that they want to aim to stay below.

Users can see this data represented on a second, more interactive glucose graph when they scroll down Lingo’s home page. A number will appear in the shaded area beneath a spike, which represents the Lingo Count for that spike.
“It’s unique to Lingo, but really that number is an indicator and a function of, how high did your spike go, how long did it last, and what was the impact that that spike had on your body,” Fohner said.
Users can analyze Lingo Count data and see how they are doing over time, as well as what time of day they tend to experience the most dramatic spikes. They can also participate in challenges and access educational resources to learn how to reduce those spikes.
Ropars said metabolism doesn’t change overnight, and everyone’s bodies work differently. He said Lingo can serve as a window into how and why a user’s glucose levels vary. But the real value of Lingo, Ropars said, is the support it can offer users as they try to establish healthy habits.
“A lot of our products today are geared toward helping people that are experiencing a chronic disease or sickness and trying to get back on track,” he said. “Here, this is the first time we’re doing a product that is helping people, improving their daily life, taking control of their health before they get sick”

It ended up being a “hawkish cut,” as expected. Still, investors managed to find a few gifts tucked betweenthe lumps of coal.
Even though the U.S. Federal Reserve lowered interest rates on Wednesday stateside, two regional bank presidents — Jeffrey Schmid of Kansas City and Austan Goolsbee of Chicago — wanted rates to stand pat.
Their cautioned was echoed in the Fed’s “dot plot” of rate projection, which showed officials penciling in just one cut in 2026 and another for 2027.
Even the Fed’s rate statement was repurposed from the December 2024 meeting, which ushered in a nine-month period without cuts until September this year.
Why, then, did U.S. markets rise after the meeting?
The biggest surprise was the Fed’s announcement that it would begin purchasing $40 billion in Treasury bills, starting Friday. That move increases the money supply in the economy. In other words, it’s a stealthy way to ease conditions, which helps support financial markets.
Next, Chair Jerome Powell dismissed speculation about future hikes.
“I don’t think that a rate hike … is anybody’s base case at this point,” Powell said. “I’m not hearing that.”
Fed officials also see the U.S economy as remaining resilient. Collectively, they increased their forecast for economic expansion in 2026 to 2.3% from an earlier estimate of 1.8% in September.
“We have an extraordinary economy,” said Powell.
And the markets may be setting up for an extraordinary finish to the year.
“The last interest rate decision of 2025 has essentially paved the way for a Santa Claus rally to end the year, and the S&P 500 is poised to exceed the 7,000 milestone in the next few weeks,” said José Torres, senior economist at Interactive Brokers.
For investors, that would count as a very decent Christmas surprise.

U.S. President Donald Trump delivers remarks on the U.S. economy and affordability at the Mount Airy Casino Resort in Mount Pocono, Pennsylvania, U.S. Dec. 9, 2025.
U.S. President Donald Trump has once again provoked outrage among his European allies, describing them as “weak” in an interview with Politico published Tuesday. Criticizing the region’s response to the war in Ukraine, Trump said: “I think they don’t know what to do.”
That comment will be jarring for Europe after its efforts to support Ukraine — efforts which Trump has frequently downplayed. Instead, Europe has had to watch on as U.S. officials have held talks with their Russian and Ukrainian counterparts on a draft peace plan for Ukraine, without a seat at the table.
A newly proposed exchange-traded fund would offer exposure to bitcoin, much like other popular ETFs tracking the world’s oldest cryptocurrency. But, there’s a twist: The fund would trade bitcoin-linked assets while Wall Street sleeps.
The Nicholas Bitcoin and Treasuries AfterDark ETF aims to purchase bitcoin-linked financial instruments after the U.S. financial markets close, and exit those positions shortly after the U.S. market re-opens each day, according to a December 9 filing to the Securities and Exchange Commission.
The fund would not hold bitcoin directly. Instead, the AfterDark ETF would use at least 80% of the value of its assets to trade bitcoin futures contracts, bitcoin exchange-traded products and ETFs, and options on those ETFs and ETPs.
The offering would capitalize on bitcoin’s outsized gains in off-hours trading.
Hypothetically, an investor who had been buying shares of the iShares Bitcoin Trust ETF (IBIT) when U.S. markets formally close, and selling them at the next day’s open, would have scored a 222% gain since January 2024, data from wealth manager Bespoke Investment Group shows. But an investor that had bought IBIT shares at the open and sold them at the close would have lost 40.5% in the same time.
Bitcoin was last trading at $92,320, down nearly 1% on the day. The leading cryptocurrency is down about 12% over the past month and little changed since the beginning of the year.
The proposed ETF underscores jockeying among sponsors to launch ETFs tracking all kinds of cryptocurrencies, from altcoins like Aptos and Sui to memecoins such as Bonk and Dogecoin. The contest has only accelerated under President Donald Trump, who has pushed the SEC and Commodity Futures Trading Commission to soften their stances on token issuers and digital asset exchanges.
Since being approved under the prior administration in January 2024, more than 30 bitcoin ETFs have begun trading in the U.S., according to data from ETF.com.

Few companies were as hot in early 2000 as Cisco, whose networking equipment served as the backbone of the internet boom.
On Wednesday, Cisco’s stock surpassed its dot-com peak for the first time. The shares rose almost 1% to $80.25, topping their prior split-adjusted record or $80.06 reached on March 27, 2000. That’s the same day that Cisco passed Microsoft to become the most valuable publicly traded company in the world.
Back then, investors saw Cisco as a way to bet on the growth of the web, as companies that wanted to get online relied upon the hardware maker’s switches and routers. But following a half-decade boom, the dot-com bubble burst just after Cisco reached its zenith, a collapse that wiped out more than three-quarters of the Nasdaq’s value by October 2002.
While the market swoon eliminated scores of internet highflyers, Cisco survived the upheaval. Eventually it started to grow and expand, diversifying through a series of acquisitions like set-top box maker Scientific- Atlanta in 2006, followed by software companies including Webex, AppDynamics, Duo and Splunk.
With its gains on Wednesday, Cisco’s market cap sits at $317 billion, making it only the 13th most valuable U.S. tech company. In recent years, the stock has badly trailed tech’s megacaps, which have been at the center of the new boom surrounding artificial intelligence.
The AI market has reached a level of euphoria that many analysts have compared to the dot-com era. Instead of Cisco, the modern infrastructure winner is Nvidia, whose AI chips are at the heart of model development and are relied up by the other major tech companies that are all building out AI-focused data centers. Nvidia has a market cap of $4.5 trillion, roughly 14 times Cisco’s current value.
But Cisco is angling to benefit from the AI craze, with CEO Chuck Robbins in November touting $1.3 billion in quarterly AI infrastructure orders from large web companies. Total revenue approached $15 billion, which was up 7.5% year over year, compared with 66% growth in 2000.
Shares of Cisco are up about 36% so far in 2025, outperforming the Nasdaq, which has gained about 22% over the same period.
